Study Lenses
The verse centers on "found", "saith", "jehovah", "turn", "captivity", "gather", "nations", and "places". It is saying that the verse draws attention to "found" and "saith", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "and ye shall seek me and find..." into verse 15's "If ye say Jehovah hath raised us...", so "found" and "saith" belong inside that flow. In Jeremiah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "found" and "saith" with trust shaped by these words, not by a vague optimism outside the passage.
